Hemp seed is a potential candidate to replace soybean meal dependency due to its rich protein and balanced amino acid profile content despite containing anti-nutrients. This study purposed to evaluate dietary heated hemp seed cake (HSC) and the addition of phytase as a substitution for soybean meal on broiler productive performances, carcass characteristics, visceral organ weight, serum biochemical and intestinal health of broiler chickens. A total of 210 unsexed Ross broiler chicks were randomly divided into 7 treatments and 6 replicates using a completely randomized design and reared for 42 days. The treatments were T1: Corn-soybean-based ration; T2: Ration containing 15% unheated HSC; T3:T2 + 1000 FTU of phytase; T4: Ration containing 15% autoclaved HSC (120 °C,10 min); T5: T4 + 1000 FTU of phytase; T6: Ration containing 15% oven-heated HSC (120 °C,20 min); T7: T6 + 1000 FTU of phytase. On day 42, the body weight and body weight gain of the T4 group were higher (P < 0.01) compared to the T2, T3, T6, and T7 groups. The relative length of the jejunum, ileum, and cecum in all HSC diets was higher than that of the T1 group (P < 0.01). Dietary T4 lowered total bacteria and E. coli and enhanced L. acidophilus population in the cecum (P < 0.01). The villus height and surface area in all HSC diets were lower than those in the T1 group (P < 0.01). Glucose and calcium levels in the T4 and T5 groups were higher than those in the T1, T2, and T3 groups (P < 0.01). It concluded that dietary autoclaved HSC has positive effects on the gut health and growth of broiler chickens compared to dietary oven-heated HSC and unheated HSC. However, the positive effects cannot match those of soybean meal and corn-based diets.
尽管大麻籽含有抗营养物质，但其富含蛋白质且氨基酸组成平衡，是替代豆粕依赖的潜在候选物。本研究旨在评估日粮中加热的大麻籽饼（HSC）以及添加植酸酶替代豆粕对肉鸡生产性能、胴体特性、内脏器官重量、血清生化指标和肠道健康的影响。总共210只未分性别的罗斯肉鸡雏鸡采用完全随机设计随机分为7个处理组，每组6个重复，饲养42天。处理组分别为：T1：基于玉米-豆粕的日粮；T2：含有15%未加热HSC的日粮；T3：T2+1000 FTU植酸酶；T4：含有15%高压灭菌HSC（120℃，10分钟）的日粮；T5：T4+1000 FTU植酸酶；T6：含有15%烤箱加热HSC（120℃，20分钟）的日粮；T7：T6+1000 FTU植酸酶。在第42天，与T2、T3、T6和T7组相比，T4组的体重和体重增加更高（P<0.01）。所有HSC日粮组空肠、回肠和盲肠的相对长度均高于T1组（P<0.01）。日粮T4降低了盲肠中的总细菌和大肠杆菌数量，并增加了嗜酸乳杆菌数量（P<0.01）。所有HSC日粮组的绒毛高度和表面积均低于T1组（P<0.01）。T4和T5组的葡萄糖和钙水平高于T1、T2和T3组（P<0.01）。研究得出结论，与日粮中烤箱加热的HSC和未加热的HSC相比，日粮中高压灭菌的HSC对肉鸡的肠道健康和生长具有积极影响。然而，其积极影响无法与基于豆粕和玉米的日粮相匹配。
